Jenkinsfiles have only become a part of Jenkins since version 2 but they have quickly become the de-facto standard for building continuous delivery pipelines with Jenkins. Jenkinsfile allows defining pipelines as code using a groovy DSL syntax and checking it into source version control which allows you to track, review, audit and manage the lifecycle of changes to the continuous delivery pipelines the same way that you manage the source code of your application.

Although the groovy DSL syntax which is called the “scripted syntax” is the more well-known and established syntax for building Jenkins pipelines and was the default when Jenkins 2 was released. Support for a newer declarative syntax is also added since Jenkins 2.5 in order to offer a simplified way for controlling all aspects of the pipeline. Although the scripted and declarative syntax provides two ways to define your pipeline, they both translate to the same execution blocks in Jenkins and achieve the same result.

A recent Gartner survey suggests that roughly 50% of the respondents planned to implement continuous delivery and DevOps by year-end 2017 in order to deliver services faster, more often and more reliably. State of DevOps Report by Puppet Labs suggests that high-performing organizations that focus on automation and DevOps are able to reduce their lead-time for delivering a change by a factor of 440 and deliver services 46 times more often. These results have helped to make DevOps adoption a mainstream enterprise IT phenomena. As a result, today we see DevOps adoption in virtually all industries and company sizes, and the perception of DevOps as a unicorn capability has long vanished.
